A common and key requirement in business applications is the ability for the user to print the information they are using in the business application. FINALLY – Silverlight 4 Beta delivers this capability. This blog will show you how to first of all print in Silverlight 4 Beta and then how to print in a useful way! The code for this blog can be found here and is built with Silverlight 4 Beta and Visual Studio 2010 Beta. Steps: 1. Create a Silverlight application project with an ASP.NET web project ......

A very useful feature in Silverlight is the ability to use duplex services, so that the server can send messages to the Silverlight client. This is really useful when the server should control the when the messages are sent and pushed to clients as opposed to the client having to manage the code to regularly poll a service to find out if the state it is interested in has changed. In this post I we will implement a simple duplex service. The service will allow a user to register to receive stock updates ......

With any complex enterprise application delivered over the web it is typical there are very complex functions that truly need Rick Internet Application interactivity with the end user and other areas where a simple web page will suffice. Similarly it is reasonable to see situations where more than one RIA component will exist on the screen at the same time. It would be great if there were an easy way for these RIA components were decoupled yet able to send messages between each other. Silverlight ......

Following my FUNdaments presentation tonight to the East Bay .NET user group on the options available to ASP.NET developers for using AJAX type methods for grabbing information/content from a server from the client side browser, the code can be found here and the presentation can be found here. Once again Beth Massi rocked on the main presentation about VB10, C# 4.0 and Visual Studio 2010. Lots of goodies to look forward to. That said it cracks me up that MSFT is adding more capabilities to facilitate ......

I am a keen believer when building applications in having a clean logical architecture with separation of concerns as much as possible – taking into account the goals of the project and the environment in which the application will be maintained. As such, when it makes sense I believe in use of MVC, MVP, MVVM etc type patterns to enable efficient development and maintenance of applications. I can testify to the worth of adopting these styles to improve the quality of products developed from my experience ......

When building applications we usually want to adopt the write once user everywhere or DRY (Don’t Repeat Yourself) goals for simpler maintenance, validation, configuration,etc etc. So for business applications the situation is usually develop a control, that can be re-used and that can have different data bound to it for the situation in which it is used. Silverlight has a fantastic mechanism – the Silverlight Property System - that manages data binding among other things. This means that the late ......

This is the final post in a four part series to demonstrate how to use the standard MSFT technologies to implement a CRUD data application in Silverlight. The steps in this post build upon those completed in part 3. The goal of this series is to show those of you who are relatively new to Silverlight how analogous building such an app in Silverlight is to say building it in ASP.NET, Win Forms or WPF. This app is built on Visual Studio 2008 SP1, SQL Server 2008, Silverlight 2.0 and the Silverlight ......

This is the first post in a series to demonstrate how to use the standard MSFT technologies to implement a CRUD data application in Silverlight. This post is beginners stuff - there’s nothing advanced here. Most readers with some experience of Silverlight will learn nothing from this post, but I want to start at the beginning so those of you who are relatively new to Silverlight can see how analogous building such an app in Silverlight is to say building it in ASP.NET, Win Forms or WPF. This app ......
